The FPX: super flexible phase stable cables up to 50GHz
FPX series super flexible phase stable RF cables mitigate mechanical phase shift during dynamic routing. The internal structure utilizes a stranded silver-plated copper conductor and a microporous PTFE dielectric. This configuration yields a velocity of propagation of 76% and a capacitance of 86.8 pF/m.
An interlayer of PTFE and a silver-plated copper outer braid provide robust >90 dB shielding efficiency. The FEP jacket ensures chemical resistance, permitting continuous operation from -55°C to +165°C. These specifications make the FPX super flexible phase stable coaxial cable series suitable for rigorous microwave environments requiring strict amplitude stability.
